Overview
Graphite carrier is a versatile material derived from carbon, known for its exceptional thermal and electrical conductivity. It is widely utilized in industries requiring robust, high-performance materials that can withstand extreme conditions. Graphite's layered structure allows it to serve as an effective support medium in various chemical and industrial processes. Due to its inert nature, graphite carrier is resistant to most acids, alkalis, and organic solvents, making it ideal for catalytic applications. Its high surface area and stability under high temperatures further enhance its utility in demanding environments.
Physical and Chemical Properties
Graphite carrier exhibits a unique combination of properties, including high thermal conductivity (up to 1500 W/m·K) and electrical conductivity. Its layered hexagonal lattice structure provides excellent mechanical strength and lubricity. The material is chemically inert, making it resistant to corrosion and oxidation at high temperatures. Graphite's density ranges between 2.09-2.23 g/cm³, and it sublimes rather than melting under standard conditions. Its insolubility in water and most solvents ensures stability in diverse applications, from metallurgy to electronics.
Main Applications
Graphite carrier is extensively used as a support material for catalysts in chemical reactions, particularly in petrochemical and pharmaceutical industries. Its high surface area and stability make it ideal for dispersing catalytic metals uniformly. In the energy sector, graphite serves as an electrode material in batteries and fuel cells due to its conductivity and durability. It is also employed in refractory materials, lubricants, and as a moderator in nuclear reactors. Emerging applications include graphene production and advanced composite materials.
Safety and Storage
While graphite carrier is generally non-toxic, its fine powder form can pose inhalation risks, potentially causing respiratory irritation. Proper handling with dust masks and ventilation is recommended to minimize exposure. Skin and eye contact should be avoided to prevent irritation. Storage requires a dry, cool environment away from strong oxidizers to prevent accidental reactions. Containers should be tightly sealed to avoid moisture absorption, which can affect performance in certain applications.
B2B Procurement Guide
When procuring graphite carrier, key specifications to consider include purity (typically 99-99.99%), particle size (ranging from nanometers to millimeters), and ash content (preferably below 0.5%). Suppliers should provide material safety data sheets (MSDS) and certificates of analysis. Bulk pricing varies based on quantity and quality, with purified forms commanding higher prices. Buyers should verify supplier reliability and consistency in material properties, especially for critical applications like catalysis or battery production.
